20 You should be comfortable with publishing Org-mode fiels to HTML already when
21 you read this. Make sure, to create the tree-style sitemap-file on export.
23 This Tutorial describes a simple technique to include published content into
24 other web applications. I use an external JavaScript treemenu library publish
25 by Marco Pratesi. This treemenu is fast and runs in all Browsers I'm aware
26 of. The techniqe could as well be adopted to other menu libs.
28 You might as well use the Menu as kind of sitemap or top menu.
30 - The homepage of Phplaymenu is here: http://sourceforge.net/projects/phplayersmenu/
31 - A demo can be found on http://phplayersmenu.sourceforge.net/demo.php
33 Here is a screenshot of a treemenu:

39 {{{BeginInfoBox}}} *Note:* Prior to Org-mode commit
40 [[https://code.orgmode.org/bzg/org-mode/commit/4892c8899e5b99d041836749fb2d1458971be55d][4892c8899e5b99d041836749fb2d1458971be55d]] (version 6.34trans), =sitemap-file=
41 =auto-sitemap= a.s.o. where called =index-file=, =auto-index= and similar. I you
42 have to work with a version released before 25th of February 2010, just
43 replace =sitemap= with =index= throughout this file.
48 The menus are read from a string of a special structure. While it is beyond
49 this tutorial to explain the usage of the menus in details, the structure of
50 this string is important.
52 Each line of the string consists of these elements:
54 : [dots]|[text]|[link]|[title]|[icon]|[target]|[expanded]
56 Everything in brackets is optional. So are any trailing bars, if empty.
58 The tree structure is represented by prepended dots.
62 : .|Top level directory without link
63 : ..|Article 1|articles/article1.html|||main
64 : ..|Article 2|articles/article2.html|||main
66 : ..|C++|snippets/c++.html|||main
67 : ..|Perl|snippets/Perl.html|||main
69 will result in either in a tree menu like this here (=[F]= is an optional
72 : - [F] Top level directory without link
82 ...or a menubar like this:
84 : .__________________________________.__________.
85 : | Top level directory without link | Snippets |

91 * Creating the menu structure when publishing
93 To create the menu structure, I use a modified version of the elisp function
94 =org-publish-org-sitemap=, defined in =Org-mode/lisp/org-publish.el=, that generates
95 the sitemap for HTML export. The function is called
96 =sr-org-notes-sitemap-complete= and defined in one of my emacs setup files.
98 Fortunately, Org-mode makes it possible to call a function after the
99 publishing process has fineshed. To make use of =sr-org-notes-sitemap-complete=,
100 add this to your publishing project's definition:
102 #+begin_src emacs-lisp
103 (require 'ox-publish)
104 (setq org-publish-project-alist
106 :base-directory "~/org/notes/"
111 :auto-sitemap t ; generate sitemap.org automagically
112 :sitemap-filename "sitemap.org" ; this is the default
113 :sitemap-style "tree"
116 :completion-function sr-org-notes-sitemap-complete
117 :menu/structure-file "~/path/to/menu-structure-file.txt"
118 :menu/link-target "mitte" ;; optional
125 Once you re-publish your project, the menu-structure file will be created.
127 * =my-org-notes-sitemap-complete=
129 #+begin_src emacs-lisp
130 (defun sr-org-notes-sitemap-complete ()
131 "Take the sitemap-file and turn it into the menu-structure
132 file for Marco Pratesi's phplayersmenu."
133 (let* ((base-dir (file-name-as-directory (plist-get project-plist :base-directory)))
134 (orig (expand-file-name (concat base-dir (plist-get project-plist :sitemap-filename))))
135 (strip-suffix (or (plist-get project-plist :base-extension) "org"))
136 (add-suffix (or (plist-get project-plist :html-extension) "html"))
137 (link-target (or (plist-get project-plist :menu/link-target) "_blank"))
138 (menu-file (or (plist-get project-plist :menu/structure-file) nil))
140 (visiting (find-buffer-visiting orig))
141 (visiting-output (find-buffer-visiting menu-file))
143 (input-buffer (find-file orig))
144 (output-buffer (find-file menu-file))
151 (throw 'sr-org-note-kb-completion-error
152 "No menu structure file provided. Giving up."))
154 (with-current-buffer output-buffer
157 (with-current-buffer input-buffer
159 (goto-char (point-min))
160 (while (re-search-forward org-bracket-link-analytic-regexp (point-max) t)
161 (let ((link (match-string-no-properties 3))
162 (text (match-string-no-properties 5))
166 (with-current-buffer output-buffer
167 (if (string-match (concat "\\(" strip-suffix "\\)$") link)
168 (setq link (replace-match add-suffix t t link)))
169 (while (setq pos (string-match "/" link pos))
170 (setq ndots (+ ndots 1))
171 (setq pos (+ pos 1)))
174 (string-match "\\(/[^/]*\\)$" link)
175 (setq sub (replace-match "" t t link))
177 (unless (string= sub old-sub)
179 (subs (split-string sub "/"))
180 (old-subs (split-string old-sub "/")))
181 (while (string= (car old-subs) (car subs))
189 (make-string ds ?.) "|" d "\n")))
190 (setq old-sub sub))))
194 (make-string ndots ?.) "|" text "|" link "|||" link-target "\n"))
195 (setq old-ndots ndots)
198 (or visiting (kill-buffer input-buffer))
200 (with-current-buffer output-buffer
202 (or visiting-output (kill-buffer output-buffer))
206 * Include the menu in existing pages
208 To actually use the result, download the Phplayersmenu library and unpack
209 it. Move the following subfolders to your webroot:
211 * =phplayersmenu-3.2.0/lib/=
212 * =phplayersmenu-3.2.0/libjs/=
213 * =phplayersmenu-3.2.0/menuimages/=
215 Also choose one of the stylesheets in =phplayersmenu-3.2.0/=. In the example
216 below, the =layerstreemenu.css= is used.
218 Adjust the file(s) you want to include the menu in. Here is an example:
220 #+begin_src html -n -r
223 <script type="text/javascript">
224 <?php include ("libjs/layersmenu-browser_detection.js"); ?>
226 <link rel="stylesheet" href="layerstreemenu.css" type="text/css"></link> (ref:tree1)
227 <script type="text/javascript" src="libjs/layerstreemenu-cookies.js"></script>
235 include ("lib/PHPLIB.php"); // taken from PHPLib
236 include ("lib/layersmenu-common.inc.php");
237 include ("lib/treemenu.inc.php"); (ref:tree2)
238 if ( @ is_file ("../intranet/navigations/org.txt") )
240 $mid = new TreeMenu(); (ref:tree3)
241 $mid->setMenuStructureFile("navigations/org.txt");
242 $mid->setPrependedUrl("../org-notes/"); (ref:url1)
243 $mid->parseStructureForMenu("treemenu1");
244 print $mid->newTreeMenu("treemenu1"); (ref:tree4)
252 What makes your menu a tree-menu, are
254 * the stylesheet ([[(tree1)][line (tree1)]]),
255 * theinclusion of treemenu.inc.php ([[(tree2)][in line (tree2)]]),
256 * the constructor used ([[(tree3)][line (tree3)]]),
257 * and the =newTreeMenu()= method ([[(tree4)][called in line (tree4)]]).
259 The (optional) [[(url1)][URL provided in line (url1)]] is prepended to all the URLs found
260 in the menu-structure file.
262 See the Phplayersmenu docs on how to create horizontal and vertical menus from
263 the same structure file.
